Japan Atomic Energy Research Institute (JAERI) (President: Kenichi MURAKAMI) has developed a Remote Surveillance Squad (RESQ), which is composed of robots designed to be dispatched to the sites of nuclear facility accidents for the collection of information. In nuclear facility accidents, there are dangers associated with the approach of humans to the sites, became evident in the case of the criticality accident at JCO. This experience created the urgent need to prepare a robot squad. Such a squad would be able to approach an accident site in place of humans in order to collect any information required for the investigation of the cause of the accident or to expedite its control and to transmit this information to accident countermeasure office. As it is required to prepare several robots and to allot various contingency functions among them in order to deal with various types of accident, JAERI has developed three kinds of robots and has allotted them the functions that are available at the current technology levels.
Initial information collection robots (RESQ-A, 2 robots): Compact, lightweight self-propelled remote surveillance robots for a quick identification of the situation at the site of an accident. The collected information includes the dose rate, audio/video, surface temperatures of equipment etc.
Detailed information collection robot (RESQ-B, 1 robot): A self-propelled remote surveillance robot equipped with a manipulator that can approach the site of an accident by opening doors and going up and down stairs in order to collect further various of information (dose rate, audio/video, surface temperatures of equipment, atmosphere data, positions of obstacles etc.).
A sample and information collection robot (RESQ-C, 1 robot): A self-propelled remote surveillance robot equipped with two manipulators that can approach the site of an accident by opening doors and going up and down stairs in order to collect contamination information and samples (gases, liquids, solids, surface contamination samples).
These robots are controlled from a control panel in a special container and the collected information is input to a computer. For the RESQ-A that features compact size and light weight for improved mobility, a portable control panel is provided separately so that the robots and control panel may be dispatched rapidly to a site by car.
